No, ATG (any version) is not freeware. You need a commercial license to run it in production, or elsewhere.

There is no license key that restricts running it. However, that in no way implies you have any right to use the software without paying for appropriate licenses. See the Oracle download pages and associated licensing terms for details.

I very strongly urge you to read the terms and conditions associated with any software you have already or do download. These are legal agreements that document any rights you have to use the software. If you have any questions I would suggest you talk to Oracle sales about how you need to use the software and what you need for appropriate licensing.

I can say that there is an item on the Oracle price list for a Developer license for ATG.

I am from Oracle and on the Product Management team for Oracle ATG Commerce.

The document item you reference is a poorly worded note in reference to license key files that used to be needed to run ATG Commerce software. Prior to Oracle's acquisition of ATG, ATG enforced licenses via a license key files. They are no longer needed. You absolutely need a license to run ATG software. It is not free.

Can you please confirm where i have keep these licence files. As we know we normallly place this files in localconfig in the ATG directory till ATG 9.1. I am not sure where i can place these files for 10.1

Hello. If we intend to have a development, UAT and production environment, how many pieces of ATG software (or license keys) must we buy?
What is the development environment like for ATG? What type of IDE is it? Eclipse?
